A multi-year research program is underway to develop and deliver spectral-based digital cameras for imaging cultural heritage at the National Gallery of Art, Washington DC and the Museum of Modern Art, New York. The cameras will be used for documentation, production imaging, and conservation science. Three approaches have undergone testing: a liquid-crystal tunable filter (LCTF) coupled with a ...

The similarity of Lippman color photography! to the wavefront reconstruction method of Gabor was noted by Denisyuk,2 who showed that by using Lippman's method to record a hologram, the reconstruction could be made in white light. Subsequent related work has been reported by van Heerden,3 Pennington and Lin,4 Friesem,5 Fleisher et al.6 and Hoffman, et aU We report the construction of holograms m...

global trend of fashion photography has adopted the modesty fashion photography as a new procedure for advertising the hijab fashion. the birthplace of this current is outside of islamic countries but it has become important to accommodate fashion and photography with religious beliefs in islamic countries. the paper tries to review the fashion photography in the field of hijab fashion concerni...

In related work, we have shown that conventional digital cameras easily can be modified to directly capture anaglyphs. Anaglyph images commonly have been used to encode stereo image pairs for viewing, but anaglyphs also can be treated as an efficient encoding of two-view image data for reprocessing. Each of the two views encoded within an anaglyph has only partial color information, but our pre...

We evaluated the effectiveness of natural color aerial photography as a tool to improve detection, monitoring, and mapping of sulfur cinquefoil (Potentilla recta L.) infestations. Sulfur cinquefoil is an exotic perennial plant invading interior Pacific Northwest rangelands. Because sulfur cinquefoil produces distinctive pale yellow flowers, we timed aerial photography for early July, when the p...

When viewing images on a monitor, we are adapted to the lighting conditions of our viewing environment as well as the monitor itself, which can be very different from the lighting conditions in which the images were taken. As a result, our perception of these photographs depends directly on the environment in which they are displayed. For high-dynamic-range images, the disconnect in the percept...

Smartphones are widely spread and their usage does not require any trained personnel. Recently, smartphones were successfully used in analytical chemistry as a simple detection tool in some applications. This paper focuses on immobilization of acetylcholinesterase (AChE) onto commercially available pH strips with stabilization in the gelatin membrane. AChE degrades acetylcholine into choline an...

Due to the rapid growth of image databases in almost every field like medical science, multimedia, geographical information system, photography, Journalism, etc., a effective and efficient technique is required to process the image .Content-based image retrieval is a technique which is used to extract the images on the basis of their content such as texture, color, shape and spatial layout. How...
